COKE-OVEN WALL STRUCTURE.

Application lcd October 25, 1913, Serial No. 333,358.

To all whom t may concern.

Be it known that l'. JosnrH van normanni.7 a. citizen of the United States. residing' in Pittsburgh, in the county of Allegheny and State of Pennsylvania. have invented a new and useful Improvement in Coke- Oven Wall Structures. of which the following is a specification.

This invention relates generally to coke oven structures and has for its essential object the provision of a joint between the end of the heating Wall of the oven and the jamb facing the end of such Wall, which joint accommodates itself heterogeneous expansion or contraction of the heatingj' Wall and ,ja-rnb, permitting such expansion or contraction without resistance, and yet preserves substantial gas-tight conditions under all circumstances, thus preventing leakage and Waste of gas from the heating walls.

A further object of the invention is the provision of an exceedingly simple and etlicient means for maintaining the jamb in its" proper position at the end of the heating Wall and for preventing endwise shifting of the jamb with respect to said heating Wall.

In the accompanying drawing, forming a part of this specification. and showing, for purpose of exemplitication a preferred form and manner in which the invention may Vbe embodied and practiced. but Without limiting the claimed invention specilically to such illustrative instance or instances Figure 1 is a fragmentary side elevation of a coke oven structure provided with the present improvements.

Fig. 2 is a vertical section of the saine taken in a plane indicated by the line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary horizontal section taken in the plane indicated by the line 33 of Fig. at.

Fig. Il is an enlarged fragmentary vertical section through the heating Wall and of a coke oven.v

In its present embodiment, the invention is incorporated in a colte oven battery of the by-product type, and for convenience the present description will be confined to this Renewed July 24, 1923.

use of the invention. Features of the invention are however readily susceptible of other uses, for example, in connection With coke oven batteries of other types; hence, it is manifest that the scope of the invention is by no means confined to the speciiic use and specific embodiment herein described.

Referring to the drawings:

There is shown a fragment of a coke oven battery, said battery being. in the present instance, of the by-product type and embodying in its construction a plurality of colring chambers 11 arranged side by side and having the usual alternating heating walls 12 provided with flame ues 13 intermediate adjacent colring chambers. The ends of each colring chamber or oven are closed by the usual doors. not shown, but of any preferred construction Well known to those skilled in the art, and when a charge Within one of the coling chambers has been coled the door of such chamber is opened or removed, and the finished colte is pushed out of the chamber and disposed of in the usual Way.

lThe heating Walls 12 extend vertically to the top 14- of the coke oven battery, said top being of the usual construction. and facing the end of each heating wall 12 is a jamb 15 consisting essentially of a vertical wall section 'substantially cru-extending along the end of the heating Wall and formed of the usual jamb bricks, as shown. The outer face of each jamb 15 is braced by a pair of vertical buck stays 16 which extend vertically beyond the top 14. of the coke oven battery. It Will be understood that the heating Walls 12 extend crosswise ofthe coke oven battery and at their opposite ends are faced with jambs such as -are indicated at 15, and that vertical buck stays are also provided for bracing the outer faces of the jambs on that side of the battery opposite to the side indicated in the drawing. The several pairs if buclr stays on opposite sides of the coke oven battery are connected together by transverse bars 17 secured to cross heads 18 mounted adjacent the upper end of each pair of buck stays.

The presentinvention relates particularly to the provision of an improved joint conwalls The flame flues 13 are located between the several tie-brick sections as shown. The several sections constituting each heating wall are constructed of silica brick, whereas the jambs 15 facing the ends of the heating wall are constructed of clay bricks. As a result of the facts that the heating walls and the adjoining jamb are formed of materials having different coeiiicients of expansion, that the jambe are exposed eXteriorly to radiation, and that the buckstays exert variable pressures upon the jamb bricks during expansion or contraction of the battery, the problem of providing a joint which will maintain substantially gastight conditions between the ends of the heating wall and yet permit the heterogeneous expansion of the jambs and heatingr walls. when subjected to coking heat has. in the past, been exceedingly diflicult or" solution. Most adhesive materials when used as fillers between the jambs and the ends of the heating walls are unable to withstand the enormous strain produced by the hetero* geneous expansion or contraction of these parts, and consequently crack under such stresses. leaving chinks and crevices which have made gas-tight conditions almost impossible.

The present invention obviates the aforesaid diliculties by the provision of a joint between the ends of each heating wall and the adjoining jamb said joint being composed of a fluent solid substantially `gastight material that is non-agglomeratie when subjected to coking heat.

A satisfactory materia-l. for this purpose is silica sand which does not agglomerate or form itself into lumps when subjected to the temperatues at the joints, and such joints may be readily formed by filling the entire space between the jamb and the end tiebrick section 22 of the heating wall with silica sand, as shown at 23. When the heating walls and the jambe expand or contract heterogeneously the sand because of its fluent nature will run into and fill up any chinks, thus maintaining constant substantial gas-tight conditions without giving rise to cracking or otherwise damaging stresses.

The joint between each j amb and the end of the heating wall is furthermore constructed. to prevent endwise slipping of the jamb with respect to the heating wall. For this purpose the ends of the liner-brick sections 19, 20 of each heating wall are formed with jogged edges 24; the jambs 15 are formed with similar or companion jogged edges 25 for engagement with the jogged edges 24 of the heating walls; the inter-lock flanged and grooved faces of the jambs and heating walls will prevent endwise movement of the jambs and maintain the latter at all times in their proper positions at the ends of the heating walls. If desired, these companion jogged edges of' the jambs and heating walls may be held together by silica or other suitable cement.l

The invention as hereinabove forth is embodied in a particular .form of construction. but may be variously embodied within the scope of the claims hereinafter made.
